[gotcha] Token-by-token streaming causes users to act on partial information before the response is complete

Buffer streaming output at sentence or paragraph boundaries before displaying it. Show a typing animation for the current in-progress sentence rather than rendering raw tokens. This delivers complete thoughts while maintaining the perception of speed.

Journey Context:
Token-by-token streaming creates a reading experience where users start interpreting and acting on information before the model has finished generating. LLMs often start with a confident assertion and then qualify or contradict it later. Users who skim the beginning may miss crucial caveats. Buffering at sentence boundaries preserves the perception of speed \(text appears continuously\) while ensuring users always read complete thoughts. The tradeoff: sentence-boundary buffering adds 50-200ms of perceived latency per sentence, but this is imperceptible compared to total generation time and dramatically improves comprehension and reduces premature action on incomplete information.
